Plasticised PVC compositions

Esters of fatty acids having the formula RCOOR 1 wherein the groups R and R 1 which may be the same or different represent alkyl or alkenyl groups comprising from 6 to 24 carbon atoms have been discovered to be used as lubricants in PVC compositions which comprise a phosphate ester as a plasticiser or flame retardant because their use reduces the evolution of unpleasant odours during manufacture of the compositions and in applications such as extrusion. The novel PVC compositions find particular value in coating of wire and cable where they reduce odour and may enable the use of a composition which does not contain any heavy metals.
